Since life began eons ago, thousands of creatures have come and gone. Some, such as the dinosaurs, became extinct due to naturally changing ecologic conditions. More recent threats to life forms are humans and their activities. Man has drained marshes, burned prairies, dammed and diverted rivers. Some of the more recent casualties of man’s expansion have been the dodo, great auk, passenger pigeon, Irish elk, and Steller’s sea cow. Sadly, we can no longer attribute the increasing decline in our wild animals and plant species to "natural" processes. Many species are dying out because of exploitation, habitat alteration or destruction, pollution, or the introduction of new species of plants and animals to an area. As mandated by Congress, protecting endangered species, and restoring them to the point where their existence is no longer jeopardized, is the primary objective of the U.S. Fish and Wildlife Service’s Endangered Species Program. [br] Which of the following would be a likely theme for the next paragraph?
选项
A、Naturally changing ecological conditions.
B、Animals that have become extinct.
C、Achievements of the government Endangered Species Program.
D、Programs that have destroyed natural habitats.
答案
C
解析
推断题型。本段提到了由于生态环境的变迁和人类活动的破坏等因素造成了一些物种的灭绝,段尾提到由国会授权,美国渔业及野生动物署实施挽救濒危物种计划且提到这一计划的主要目标。根据逻辑推理,下段应提及政府实施这一计划所带来的变化,因此选项C.“政府实施这一计划所带来的成就。”应为答案。
